My father is American, but my mother is Spanish and I have lived abroad longer than I have lived in both countries (Moscow, Russia, Singapore City, Sinagpore, and San Juan, Puerto Rico).
I am currently a student at Babson College, but you should not worry as:
1. I hate messes, so your apartment will look better when I leave than when I arrived
2. I have lived alone for months at a time because of internships (generally in London)
